Watch: Kelly Rowland Sheds Some Tears While Singing 'Dirty Laundry'

Things got a bit emotional when Kelly Rowland sang her song "Dirty Laundry" on Sunday in front of a Washington D.C. crowd. She started to cry in the middle of the song before the audience encouraged her to finish and she did to great applause.

But why did the Destiny's Child alum get all choked up? As the song's title suggests, the song is an opportunity for her to air out her "dirty laundry." She sings about being jealous of her former bandmate Beyoncé and being in an abusive relationship. Watch the video of the performance below.

Rowland is currently on her "Lights Out" tour and can be seen on the forthcoming season of The X Factor as a new judge alongside Simon Cowell, Paulina Rubio, and Demi Lovato.
